Heat Emission: How it Works

 

Understanding the way heat works

All matter is made up of molecules and atoms. These atoms are always in different types of motion: translation, rotational, vibrational. This motion generates heat, which is also referred to as thermal energy. All matter has thermal energy and the more motion the atoms or molecules have, the more heat or thermal energy they produce.

 

How does temperature work?

When it comes to the movement of atoms and molecules, some move faster than others. Temperature is an average charge of energy for all the atoms and molecules in each system. Temperature is autonomous to the amount of matter present in the system. It’s simply an average of the energy in the system.

 

The way heat is transferred 

Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection need matter to transfer heat. If there’s a temperature difference between two systems, heat will always find a way to transfer from the higher to lower system. 

 

Conduction 

Here, heating occurs via direct contact between heat source and object. Conduction is the transfer of heat between materials that are in direct contact with each other. The better the conductor, the faster heat will be transferred. For instance, metal is a good conduction of heat. 

Essentially, when a substance is heated, particles are given more energy, and vibrate more. These molecules then bump into nearby particles and allocate some of their energy to them. This cycle then continues and passes the energy from the hot end down to the colder end of the substance. 

 

Convection

This kind of heating occurs through air or liquid and is initiated by a heat source. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then replaces warmer areas which have risen higher. This results in a nonstop circulation pattern. A good example of convection can be seen in the atmosphere: the earth's surface is warmed by the sun, and warm air rises and cool air moves in. Another example of these convection currents is when you boil water in a pot.

 

Radiation

This is a method of heat transfer that doesn’t rely on any contact between the heat source and heated object, as in the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation, usually called infrared radiation. This is a form of electromagnetic radiation. No mass is exchanged and no medium is necessary in the process of radiation. 

Heat is given off by an object whose temperature is higher than that of the surrounding environment – as with the sun, open flames, or infrared radiant appliances. Objects obtain infrared radiance given off by the source and are immediately heated. Varma Tec equipment exploits this latter mechanism: by directly heating the objects or persons it targets but not the surrounding air. This principle makes for a highly functional system. The heat can be projected to zones without dispersal or waste. 

Varma Tec appliances feature a broad spectrum of products, and are made up of a vast range of items, to fit in with any number of applications.
